多种勘查手段在煤矿自燃区探测的应用研究——以山西宁武县石窑沟村露天煤矿为例

研究区位于山西省宁武县石窑沟村,为了探明该区域煤矿自燃区,采用收集资料、走访及野外地质调查、热红外遥感、高精度磁测、地面活性炭氡气测量初步解译推断出区内露天煤层自燃火区的范围、影响深度及类型,最后通过钻探对解译推断进行验证,结果显示数据基本准确、可靠,为后期火区治理工程提供了准确的基础数据.研究工作表明采用这些综合勘查...

Research on application of various exploration methods in detecting spontaneous combustion area of coal mine, taking Shiyaogou village open-pit coal mine in Ningwu of Shanxi as an example

The research area is located in Shiyaogou village,Ningwu County,Shanxi Province In order to nd out the spontaneous combustion area of coal mine in this area,data collection, eld visit & geological survey,thermal infrared remote sensing,high-precision magnetic survey and surface active carbon radon gas survey are used to preliminarily interpret and infer the scope,in uence depth and type of spontaneous combustion area of open-pit coal seams in this area Finally,the interpretation and inference have been veri ed by drilling and the veri cation results show that the data are basically accurate and reliable,which provide accurate basic information for later fire control The research work shows that these comprehensive exploration methods have certain application prospect in detection of hidden re area in mines,and will provide a reference basis for prospecting the spontaneous combustion in open-pit coal seam of other areas
